Hello everyone,
I found the subroutine below from a script that takes a string of text and builds a regular expression out of it and incorporates that into a rule for SpamAssassin. It's worked quite well for my needs, but the script has led to a few questions about the code and regex's.
My questions are:
1) Are the characters escaped in the subroutine *all* the characters that *should* be escaped in a regex?
2) The author seems to think "this is crap code, there will be a better way to do this".....thoughts, comments, suggestion on other ways this can be done?
#escape stuff that would otherwise be regexp special
#this is crap code, there will be a better way to do this
sub escapebad {
my $string = $_[0];
$string =~ s/([\\\/[EMAIL PROTECTED](\)\<\>])/\\$&/g; #bad cha
rs turned good
return ($string);
}
Also anyone interested in the script for generating SpamAssasin rules, let me know and I'll send you a copy.
Thanks for any help, Kevin
If you have a string that is going to need escaping, consider using /\Q$string\U/ to handle quoting regex special chars.
Regards, Randy.
